Progression of LV DFP in disease. Diagram shows pattern progression in hypertension. Hypertension of sufficient duration with preserved systolic function causes an R pattern. If there is improvement the pattern could revert to normal. If there is no improvement the pattern could remain as R pattern with probably an increase in EFT. With preserved systolic function it will never progress to C pattern – implying another disease. However in the event of a myocardial infarction systolic dysfunction occurs and the patterns will progress from 1 to 3+ depending on the severity of systolic dysfunction. Here it is better not to call it a progression of 'diastolic dysfunction'.
